CK_RING_SIZE(3)

💖 CK_RING_SIZE(3) — the "how many besties are in the queue rn" page 💖

okay so this is a page from the Concurrency Kit manual, aka ck_ring_size(3), and it's lowkey the cutest little function ever. she counts things. that's the whole job. slay. 🎀

🌸 NAME 🌸

ck_ring_size — returns the number of pointers currently enqueued in a bounded FIFO ✨

like. she looks at your ring buffer and goes "there are this many pointers in here bestie" and that's it. main character energy fr fr.

📚 LIBRARY 📚

Concurrency Kit — link it with libck, i.e. -lck. 💜

✨ SYNOPSIS ✨

#include <ck_ring.h>

unsigned int
ck_ring_size(ck_ring_t *ring);

she takes exactly one thing: a ck_ring_t * called ring. and she hands you back an unsigned int. no drama, no extra args, no notes. 💅

🦋 DESCRIPTION 🦋

The ck_ring_size(3) function returns the number of pointers that are currently enqueued in the buffer pointed to by ring. 🫶

that's it. that's the function. it's giving "one job and she ate". the count is the pointers sitting in there right now, and the buffer in question is the one ring points at. 👑

ngl, "currently" is doing a lot of heavy lifting there — this is a concurrency thing, so what's in the ring can change under you. that's just the vibe of the whole library, bestie. 💀
